How to create an event that is triggered by a prameter?

David L Wright II

I am extending the datagrid by adding 3 parameters that can be set both
during design time and run time. How can I develop an event that is
executed at run time based on the value of the parameter?

Hi,

Create a windows hook to look for the WM_DEVICECHANGE message.

Hi,

Sorry posted the last to the wrong message. Try something like
this.

Private mstrParameter As String
Public Event PropertyChanged(ByVal e As EventArgs)

Public Property MyParameter() As String
Get
Return mstrParameter
End Get
Set(ByVal Value As String)
mstrParameter = Value
If Not Me.DesignMode Then RaiseEvent PropertyChanged(New
EventArgs)
End Set
End Property

Ken,

Your example was exactly what I was looking for and it's quite simple.

Thanks,
